If someone wants to talk to me via email or text, sure. I don't think those basic services are universally losing privacy any time soon. Lemmy too now, since it's decentralized.

But if someone wants to talk to me via a Discord subsitute, I'm not going to bother. Maybe I'm weird, but I don't feel a moral impetus to download a new app just so I can talk to one particular person in the format they prefer. They don't have to move to Discord to appease me either, because text and email are suitable substitutes that I'm sure both parties arleady have.
